Floyd D. was the Heritage technician that arrived exactly on time this morning and did an outstanding job in fixing our problem. He gave us several solutions to solve our issue as he was performing the work. He was extremely knowledgeable and personable. The issues were solved very efficiently and he cleaned everything up perfectly before leaving.

Jeremy just came out – after calling me with his exact ETA and took a look at what needed to be done. Unfortunately he had to deliver some hard but not unexpected news. about our heating system. He supplied me with detailed options and explanations and also talked to my husband over the phone at work to make sure we had all the information we needed. Jeremy was kind, professional and very patient. I recommend Heritage ALL the time and will continue to do so.
